Key Parameters

Substitute Part Grouping Explanation

Substitution of the AFK337M06E16B-F is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance: 330 µF (exact match)
• Voltage Rating: 6.3 V (exact match)
• Tolerance: ±20% (exact match)
• Lifetime: 2000 Hrs @ 105°C (exact match)
• Operating Temperature: -55°C ~ 105°C (exact match)
• Polarization: Polar (exact match)

Mechanical Equivalence Requirements:

• Package Type: Radial, Can - SMD (exact match)
• Physical Diameter: 0.315" (8.00 mm) (exact match)
• Physical Height: 0.256" (6.50 mm) maximum seated height (exact match or lower)
• Mounting Type: Surface Mount (exact match)
• Surface Mount Land Size: Compatible with 8.30 mm x 9.50 mm footprint

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level 1 (Unlimited)

All three substitute parts meet these criteria and are sourced from active manufacturers with current production status.

Parameter Comparison

Engineering Selection Recommendations

EEE-FK0J331P (Panasonic Electronic Components)

This substitute is the primary equivalent for the AFK337M06E16B-F. Both parts share identical electrical specifications (330 µF, 6.3 V, ±20%, 2000 Hrs @ 105°C), matching physical dimensions (8.00 mm diameter, 6.50 mm height), and equivalent ripple current ratings at 120 Hz (225 mA). Both are AEC-Q200 rated for automotive applications and ROHS3 compliant. The part is in active production with 5100 units in stock. The Panasonic FK series is established in automotive bypass and decoupling applications.

EEE-FK0J331AP (Panasonic Electronic Components)

This substitute is functionally equivalent with identical electrical and mechanical specifications to the primary part. It differs in ripple current at 120 Hz (195 mA versus 225 mA), which is lower than the original specification. This part is also AEC-Q200 rated and ROHS3 compliant, with 4522 units in stock. Selection of this variant is appropriate where the lower ripple current specification is acceptable for the application.

UCL0J331MCL6GS (Nichicon)

This substitute meets all critical electrical equivalence requirements (330 µF, 6.3 V, ±20%, 2000 Hrs @ 105°C) and physical dimensions (8.00 mm diameter, 6.20 mm height). The Nichicon UCL series offers superior electrical performance with lower impedance (180 mOhm versus 260 mOhm) and higher ripple current capability at 100 kHz (500 mA versus 300 mA). However, this part is not specified as AEC-Q200 rated. Selection is appropriate for general purpose applications where automotive qualification is not required. The part is in active production with 3720 units in stock.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK0J331AP be used as a direct replacement for AFK337M06E16B-F?

A: EEE-FK0J331AP is electrically and mechanically equivalent with one exception: ripple current at 120 Hz is 195 mA compared to 225 mA in the original part. If the application circuit operates at or below 195 mA ripple current at 120 Hz, this part is a direct substitute. Both are AEC-Q200 rated and ROHS3 compliant.

Q: What is the difference between the two Panasonic FK series parts?

A: EEE-FK0J331P and EEE-FK0J331AP are both Panasonic FK series 330 µF 6.3 V capacitors with identical electrical and mechanical specifications. The primary difference is ripple current at 120 Hz: EEE-FK0J331P is rated at 225 mA (matching the original part), while EEE-FK0J331AP is rated at 195 mA. Both are AEC-Q200 rated and in active production.

Q: Is the Nichicon UCL0J331MCL6GS suitable for automotive applications?

A: The Nichicon UCL0J331MCL6GS meets all electrical and mechanical equivalence criteria for the AFK337M06E16B-F. However, it is not specified as AEC-Q200 rated. This part is suitable for general purpose applications. For automotive applications requiring AEC-Q200 qualification, the Panasonic FK series parts (EEE-FK0J331P or EEE-FK0J331AP) are the appropriate selections.

Q: Will the Nichicon part fit the same PCB footprint?

A: The Nichicon UCL0J331MCL6GS has a physical height of 0.244" (6.20 mm), which is 0.012" (0.30 mm) shorter than the original AFK337M06E16B-F at 0.256" (6.50 mm). The diameter remains identical at 0.315" (8.00 mm). The part will fit within the same PCB clearance envelope and is mechanically compatible.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: capacitance (330 µF), voltage rating (6.3 V), tolerance (±20%), lifetime (2000 Hrs @ 105°C), operating temperature range (-55°C ~ 105°C), package type (Radial, Can - SMD), physical diameter (8.00 mm), physical height (6.50 mm maximum), mounting type (Surface Mount), RoHS3 compliance, and MSL 1 rating. All three substitute parts meet these criteria.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. EEE-FK0J331AP, EEE-FK0J331P, and UCL0J331MCL6GS are all supplied in Tape & Reel (TR) format, suitable for automated assembly processes.

Q: What is the inventory status of substitute parts?

A: EEE-FK0J331P has 5100 units in stock, EEE-FK0J331AP has 4522 units in stock, and UCL0J331MCL6GS has 3720 units in stock. All three parts are in active production with adequate availability.
